Looking back at Posy Simmonds

As an exhibition of Posy Simmonds's work from the 1970s, 80s and 90s opens at the Guardian's offices, we take a look at some of her finest work.

'The Guardian did not invent Posy Simmonds, but it was a magical collision of a moment in time, the paper, its readers and Posy's brilliant comic pen that made her a household name far beyond its pages.' Liz Forgan, Chair of the Scott Trust
